Many children are back to school for the first time in two years - but concern about unexploded devices in and around schools is still high.
At least 320 schools have reopened in eastern Mosul and nearby towns - allowing around 258,000 children to return to education while fighting continues in the west of the embattled Iraqi city.
Some of the children had been out of school for more than two years, with girls largely banned from getting an education by the terror group Islamic State.
In February, UNICEF provided learning materials including science and maths kits to 87 of the East Mosul schools, reaching 73,780 children including 31,890 girls.
The United Nations children's agency said the need for furniture, teaching materials, and teacher training remains a challenge.
Concern about unexploded devices in and around schools is high. But with only a limited number of agencies authorised to deliver Mine Risk Education (MRE) sessions, the authorities are concerned.
In Anbar province, MRE took place in 50 schools, with awareness and safety messages reaching an estimated 25,000 students, including about 45% of girls.
Paul St. John Frisoli, a senior education technical adviser on the Middle East region for the International Rescue Committee, said schools in Mosul can save children's lives by giving student, teachers, school staff and parents crucial life-saving information about mine awareness.
In a blog for Refugees Deeply, he added: "IRC staff deployed into recently retaken villages and displacement camps around Mosul have observed high rates of distress among children and families.
"Education can help children cope with the consequences of conflict by providing a secure, predictable and nurturing environment.
Having access to education offers children hope for and a sense of control over their future during crisis."
Since February 19, more than 31,500 people - including 14,800 children - have been displaced from West Mosul. The majority of people have been sent to new IDP camps in south Ninewa.
In January, 70 schools reopened in Mosul. Hessam al-Din Abar, a representative at the Provincial Council in Nineveh, where Mosul is the capital, said schools had been turned into places for terrorists to train new recruits and promote extremism.
Many families would not allow their children to attend schools while ISIL - which seized the city in 2014 - was controlling them. An estimated 3.5 million Iraqi children are missing out on education.
